Principle of Superposition and Stationary Waves
According to superposition principle, if two or more waves are travelling in a medium at the same time, then the resultant displacement of waves is equal to the vector sum of individual displacement of the wave. This note provides us an information on principle of superposition and stationary waves.
Reflection, Refraction, Diffraction and Interference of Sound Waves
Sound waves are reflected from the surfaces like light waves, obeying laws of reflection; angle of incident is equal to the angle of reflection. This note provides us an information on reflection, refraction, diffraction and interference of sound waves.
